Even I have explained some reasonable electric sharpeners which are really affordable and offer the best quality sharpening every time. Now let me talk about how electric sharpeners are best than others?

Time-Saving: If you compare an electric sharpener with a sharpening stone then, of course, it is a time-saving machine because it does the perfect job by using a powerful motor and abrasives belt. You just need to drag the blade on the sharpening slot. Even you will no need for any manual sharpening angle.

No Skills Required: If you use a sharpening steel or rod then you have to know everything about it. Because without the right sharpening angle you may lose the blade’s edge. But the electric sharpener has an automatic sharpening function and angle that helps beginners if they don’t know how to sharpen a knife?

Does not Damage Knives: There are many expensive Japanese and European style blade which required high care and maintenance. This care can extend the edge retention and performance of knives. But only electric sharpeners have Diamond abrasives and ceramic polishing wheels which can give you a nice razor-sharp and clean blade.

Suitable for Different Knives: Many sharpeners can handle only kitchen and hunting knives. But an electric sharpener can handle all kinds of kitchen knives, serrated knives, butcher knives, paring knives, fillet knives, boning knife, Japanese knives, hunting knife, pocket knives,  skinning knives, and many others. So if you need to sharpen various knives then an electric sharpener is the right choice for you.

How Electric Knife Sharpener Works?

The main question of how an electric knife sharpener works? is the question that comes to the mind of any person. The electric sharpener provides the user with ease in terms of usage. You just have to switch it on and the adjust abrasives that do the grinding task to smooth out the distorted straight edge of a knife.

So the sharpener motorized on the wheels that spin against the dull knife smoothing out the edges. As we know that it is much Annoying to use dull knives in the kitchen. So a Pro electric knife sharpener will give you the best opportunity to sharpen your kitchen or commercial knives. But there are only a few sharpeners that can handle the sharpness of hunting and other knives.

When the kitchen knives are inserted inside the slot wheels with abrasives then it makes the sharpening task easier. The task of the sharpening process is easy as you don’t need to apply any force to get the work done. With light pressure, you insert the knife in the slots and pull the knife back after inserting slowly so that both sides of the blade are smoothened.

In addition, most electric sharpeners have 3 to 4 different grinding slots. Each slot provides different coarseness to provide variety in sharpness. You can get the required sharpness as you wish. The electric sharpener has the ability to narrow the angle of a knife blade and without any stoppage convert a western blade from 20-degrees to a 15-degree sharpening angle.

It has guides loaded with springs restricting the movement of the knife. Due to this feature, the whole length of the knife blade gets smoothen making great contact with the abrasives at a precise sharpening angle. Furthermore, by sharpening your knife with an electric sharpener, there won’t be daily chaos of sharpening.

How You Should Choose The Best Electric Knife Sharpener?

kitchen knife sharpener

To sharpen your knife if you are interested to buy the best electric knife sharpener then you should consider some features which may give you the best safety and Convenience. In your budget, you should choose those sharpeners that can fulfill your needs. Let’s see which thing you should consider

Sharpening stages

Most electric sharpeners available with 2 or 3 stages for sharpening kitchen and outdoor knives. Three-stage sharpeners have different slots such as coarse, honing, and polishing. This means these features will give you more in getting razor-sharp, clean edge, and better shiny blade but it may be expensive and are ideal for professionals.

On the other hand, two-stage sharpeners are very simple but don’t have much precision like 3 stage sharpener. It provides slightly the same performance and is less expensive. If you are a home cook, then it would be the best choice for you as it is easy to use and maintain.

Sharpening wheel

If you want to choose a durable electric sharpener, the high-quality sharpening wheel is the best option for you. To sharp the edges of knives, you should purchase the sharpener with a sharpening wheel that can be spun at a high speed. To get sharp edges, angle the edge toward the sharpening wheel. 45 degrees is the best angle that is used in sharpening a knife’s blade.

Sharpening abrasive

People love electric sharpener because it has either diamond abrasive, or Sapphirite sharpening wheel. Both features help to deliver a clean and razor-sharp blade. The diamond abrasive is very effective because it’s the hardest material. Even if you have a deeply dull knife then this function will give your knife a previous super sharp edge.

Other hand Sapphirite sharpening wheel is a good alternative of diamond abrasive. It is the same ultra-hard material that uses by the most professional knife sharpening shop. Especially this feature is available with 2 stage sharpener and it’s very affordable. But it will depend on you that what kind of knife you want to sharpen and which feature will be best in your budget?

Angle guide

An angle guide is very important, especially for beginners. Even I would say sometimes professional chefs need a special device to measure the right angle. This function makes knife sharpening easier and popular than a manual. So if you want to use an electric sharpener for your first time, then you should look at it.


While choosing the best electric sharpener, the best design bevel is the main feature. Bevel is the shape of the edges of a blade. Choosing the right angle to sharpen a knife is a very important compromise among durability and sharpness of the edge.

The bevel angles depend on how you will use your knife either for filleting a fish or for chopping vegetables or fruits. From the above examples, it is very easy to check how every task required a unique edge.


Versatility is not very important if you need to sharpen only kitchen knives. But if you want to sharpen several knives in one machine then you should choose a sharpener that have the ability to handle various kitchen and outdoor knives.

Even you should choose a sharpener that can handle stainless steel blades, Japanese knives, or bread/serrated knives. But if you need a sharpener only for a kitchen knife, then you should avoid a versatile sharpener because that would expensive.


The electric sharpener is not very lightweight, because it has a motor, grinding stone, and made from high-quality materials. If you need to carry it from one place to another, then choose a lightweight sharpener.

Unfortunately, without electricity, you can’t use it outdoor. But above I have explained some sharpeners that operate by the battery. That means if you charge them fully, then you can use them outdoor and you will no need any electricity.

Safety features

The electric sharpener is one of the safest ways to sharpen a knife. Because this machine designed to reduce any injury during sharpening. Some sharpeners have a special handle to hold it by hand while using it.

But if the sharpener has a special suction cup on the bottom then it will fit in any situation and will prevent moving the sharpener. That’s why you can sharpen your knife with ease and you will no need to hold the sharpener.

Ease of maintenance

Convenience and ease of maintenance should be the factors to consider while choosing the best knife sharpener. Time-consuming steps, mess countertops, and inconsistent results are the reasons that show avoidance of whetstones. In that particular case, use V. notch or electric sharpener as it gives ease of maintenance of sharpness of knives and faster result.
